Emissions

The E07Z engine was designed to meet Japanese domestic emissions regulations in effect from 1990 through 1998. All models from this era are compliant with the federal 25-year import exemption from EPA and DOT regulations in the United States. No smog testing is typically required for off-road use. Check your state's DMV requirements before registering for street use, as some states apply their own emissions rules to imported vehicles.
